NTN NS4934 Automatic Transmission Extension Housing Seal

The NTN NS4934 is an automatic transmission extension housing seal designed to prevent fluid leaks at the rear of the transmission where the driveshaft or tailshaft exits the extension housing. NTN is a globally recognized bearing and seal manufacturer known for producing precision components to exact OEM specifications.

Key Features:

• Precision-engineered lip seal construction for a reliable, leak-free fit
• Manufactured to OEM dimensional specifications for direct replacement
• Resistant to transmission fluid and heat for long service life
• Helps maintain proper transmission fluid levels by sealing the extension housing output
• Designed for straightforward installation as a drop-in replacement

The NS4934 extension housing seal is an essential maintenance component. A worn or damaged seal can allow transmission fluid to leak onto the driveshaft or contaminate other drivetrain components, leading to low fluid levels and potential transmission damage. Replacing this seal at the first sign of leakage helps protect the transmission and maintain optimal performance.
